I just want to have a general idea. When I drink water, any kind, and any temperature, my stomach hurts. It does this even after sports, when I wanna rehydrate. The last time, which was 4 days ago, I drank a full bottle of water (250 ml) and my stomach still hurts from this day... Do you have any idea of what I have? By the way, it started doing this 2 years ago, and I still drink water, if that helps you in any way!
